NO, NO2, N20, N2O3, N2O5.

Answer 1

Explanation:

When any N compound is applied to a submerged paddy field, it is lost through leaching, denitrification, volatilization and runoff. Of the total N loss, leaching contributes about 30–50%, mostly as nitrate, denitrification, about 10–30% as N2 and volatilization, about 2–30% as ammonia.
